Semiconductor Temperature Control Fluid CL7500

Features Of Semiconductor Temperature Control Fluid CL7500

1. Ultra-low volatility and negligible vapor pressure at operating temperatures (−40 °C to +180 °C), minimizing fluid loss and system contamination.

2. Exceptional thermal stability with no measurable degradation after 1,000 hours at 150 °C under inert atmosphere.

3. Non-corrosive to copper, aluminum, stainless steel, and common elastomers (EPDM, FKM, silicone) used in semiconductor thermal management systems.

4. Halogen-free formulation compliant with IPC-J-STD-020 and JEDEC moisture sensitivity level (MSL) requirements for cleanroom environments.

5. Low surface tension (21.5 mN/m at 25 °C) enabling uniform wetting and efficient heat transfer across microchannel cold plates.

Typical Applications Of Semiconductor Temperature Control Fluid CL7500

1. Temperature stabilization of high-power laser diodes and VCSEL arrays in photonic integrated circuit (PIC) test platforms.

2. Coolant for wafer probers and automated test equipment (ATE) thermal chucks requiring precise ±0.1 °C control.

3. Heat transfer medium in immersion cooling systems for advanced packaging substrates (e.g., 2.5D/3D ICs, chiplets).

4. Thermal interface fluid in liquid cold plate assemblies for power amplifiers and RF transceivers in 5G mmWave base stations.

5. Process fluid in temperature-controlled bonding and reflow simulation chambers for die attach and underfill curing validation.

Semiconductor Temperature Control Fluid CL7500 – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for CL7500?

A: CL7500 is a proprietary multi-component formulation; individual components are disclosed under NDA, and the mixture does not carry a single CAS number. Full compositional disclosure is available under signed CDA for qualified engineering evaluation.

Q2: Is CL7500 suitable for direct immersion of bare silicon wafers or open-die assemblies?

A: Yes — CL7500 has been tested per SEMI F21-0302 for particle generation and metal ion leaching (<5 ppt Cu, Ni, Fe); however, post-immersion rinse with ultra-pure water is recommended before metrology or bonding steps.

Q3: How does CL7500 compare to standard silicone oils (e.g., Dow Corning 200 Fluid) in semiconductor applications?

A: Unlike silicone oils, CL7500 contains zero volatile cyclic siloxanes (D4–D6), eliminates silicone residue risk on optics/sensors, and offers superior oxidative stability above 120 °C without antioxidant depletion.

Q4: Does CL7500 meet NASA ASTM E595 low-outgassing requirements for space-grade electronics testing?

A: Yes — CL7500 achieves ≤0.8 % TML (Total Mass Loss) and ≤0.05 % CVCM (Collected Volatile Condensable Materials) at 125 °C/24h per ASTM E595, qualifying it for Class A low-outgassing applications.

Q5: Can CL7500 migrate into or extract plasticizers from PVC tubing commonly used in lab coolant loops?

A: No — CL7500 shows no measurable swelling, extraction, or plasticizer migration from medical-grade PVC (USP Class VI) or Santoprene® tubing after 1,000-hour soak at 85 °C, as confirmed by FTIR and gravimetric analysis.
